' SNOW-MELTING DEVICE.

To all whom. it may concern:

Be it. known that I, CHARLES B. MANN, citizen of the United States, residing at San Diego, in the county of San Diego and State of California, have invented. certain new and useful Improvements in Snow-Melting De vices; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appcrtains to make and use the same.

My invention relates to a snow melting device and has for its object the provision of improved means for removing the snow; from the streets by converting thesame into water.

Further objects and advantages of the in- .in the detailed dc- In the accompanying drawings Figure 1. represents a side view ofthe machine, Fig. 2 a sectional and POIIHPUCl'lVO view, and Fig. 3 a top plan view.

Referring more particularly to the drawings numeral 1 is a fire box,constructedof v sheet iron, 2 is an extension of thefire box,

3 is a platforn'i upon the rear of the ma chine, t represents tubes located between the the box 1 and smoke box 5, the chimney (l is an exhaust for the smoke box, 7 is a water supply tank and 8, a fuel which pipes 10 and lllead to burners 12.

Fire box 1 is surrounded upon front, bottom, sides, and'rear by an inclosed air space 13 to reduce loss of heat by radiation. The snow, when melted, may be removed through the outlets 14, upon either side of the machine, to which hose may be attached that will convey the water to the gutter. 7

' The machine is mounted upon wheels '15 at the rear and one or more sn'iall wheels '16, at the Forward end of the tire box, having swivel trucks, to permit the machine to turn street wrners easily.

vided with shoes 24-, which allow scoop 18 to slide over trolley tracks and the like.

9 is a suitably braced bar extending rearwardly and is for thepurpose of driving the machine by means of horses.

, It will be seen that in the operation of this machine, the snow may be rapidly and easily gathered up and reduced 'at onceto water, and the same being warm and being com veyed to the gutter will rapidly disappear. The tubes are arranged in three tiers, the middle tier of tubes alternating with those upon the top for the purpose of presenting as much as possible of the heatirg surface to the snow. The outlets 1 are provided -wi'th valves, thereby allowing the machine to deliver the water to only one side of the street. if desired.

From the foregoing description it; will be seen that simple and etlicient means are herein provided for accomplishing the objects of the invention, but. while the elements shown and described are well adapted to serve the purposes for which they are to be understood thatthc invention is not limited. to the precise construction set forth, but. includes within its puriview such changes as may be made within the scope of the appended claims.

I claim:

1. A snow mcltingtdevice, of the character describiul, comprising a firebox, a series of fuel oil burners therein, oil and water supply tanks for the burners, a plurality of melting tubes above the lire-box, an lI'lClillCt'l scoop forward of the tire-lmx, a swivel jointed truck underneath the fire-box,'and means to force the snow over the melting tubes, in combination. with a. braccdbeain for applying motivepower at the rear.

2. A snow melting device of the character described, comprising a tire-box, a. series of fuel oil burners therein, valves for regulating the burners, oil and water supply tanks, a plurality of meltin horizontal tiers above t re tire-box, the tubes of one tie altcrnat ing with the next, an inclined scoop forward ot the tire-box, a hinged joint that permits said scoop to follow irregularities oi the street shoes at the forward end of the scoop, and means to cut, and force the snowover the melting tubes.

45. snow melting device. comprising an inclosed jacketed lire-box fuel oil l'mrners therein, a series of return tubes placed horiintended, it is zontally over the fire-box, and means to cut valve controlled outlets for delivering water and force the snow over the melting tubes. at either eide of the machine.

4. A snow melting devlce, comprisin a I In testlmony whereof, I affix my signareetangular melting box, a fire-box un erture,1n presence of two Witnesses.
